To celebrate 30 years of the Ultima franchise and 14 years of Ultima Online, EA and BioWare Mythic have launched a new Ultima Forever site that lets you download the original PC version of Ultima IV: Quest of the Avatar for free! If you've never played this classic game, here's a brief description from the site:

"Released in 1985, Ultima IV was the first in the 'Age of Enlightenment' period of Ultima games. It truly was a step forward in gaming, as it focused not on defeating some generic evil force with traditional “hack & slash” gameplay, but offered a story-driven quest based on ethical dilemmas presented to the player in an attempt to achieve enlightenment."
